Kool Keith - Infamous 

Keith was making music before G Rap, KRS-One and Rakim and the basement tapes can prove that claim, 1984-1990. Damn your comment is old.

Doom up there too

but yea top 2 for sure also, Prolific as ever, production unmatched in the game by him self or who he hoses to work with. he gets vile near the end. Moosebumps was a disapopintment and there are quite a few sex related tracks I dont care for but when he is on point his shiz is Ultra

Agreed, Then Rakim, Bumpy Knuckles, and Motion Man

Also Busta Rymes, Geto Boys, Wu Tang

mack awack You got it man
